Found a big upgrade for my wand last night, too. +2300 dps just from that one item. I might have paid around 20, gold (?). I can't remember, but it was relatively cheap for such a big boost in dps. Now, my wizard is up to around 8290 damage.
The AH finally stopped lagging and I received the "entry level" L60 wand (~600 dps) that I bought for ~70k gold. That price isn't too bad, I think. 1000+ dps weapons are 500k gold and above.
I need to be diligent in selling my stuff on the AH.
